Berzerk (along with Omega Race) was to follow in
the Arcade Game series in 1982 (based on Stern's Berzerk
arcade game). (Previous games of course where Donkey Kong,
Frogger, Galaxian, Pac
Man, Ms. Pac Man, and Zaxxon.
Donkey Kong Jr. should probably be there, but since they
just took Nintendo's DK Jr instead of using the prototype they came up with,
I don't really consider it part of the line). This mock-up was created and photographed
for the 1982 toy catalog distributed at Toy Fair and other locations, but it
was most likely a non-working sample used to show how the game looked, I don't
believe any working version where ever produced. Unfortunately, this game never
made it into production.
